LISTER.

Application filed May 14, 1914;.

To all whom it may concern Be it known that EDWARD HEYLMAN, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Listers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in listers and particularly to means for raising and lowering the beam and siinultaneously controlling the feeding mechanism to throw the same out of operation when the beam is raising and into operation when the beam is lowered,one object of my present invention being to so construct the means which control the operation of the feeding mechanism, that the condition of the clutch members which constitute part of the con trolling means, to effect com lete engagement with each other or absolute disengage ment from each other, shall be insured under all conditions of use of the machine,

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed outin the claims.

In the accompanying drawings, Figure l is a side elevation'of a machine embodying my improvements; 2 is a plan view; Fig. 3 is a transverse sectional view, and Figs. l and 5 are e: larged fragmentary views partly in sect-ion and partly in elevation.

1 represents an arch axle having its ends journaled in the hubs of carrying wheels 2, 3. The rear end of a pole or tongue l is mounted upon the top of the arch axle and braces 5, 8 connect a forward portion of said pole or tongue with the arch axle in proximity to the lower ends of the upright Specification of Letters Patent.

provided with a clevis 13, with which the lower end of a link 14 is pivotally connected. The upper end of this link is provided with an elongated slot 15 for the passage of a pin 16 which pivotally connects said link 141- with the lower end of an upper link 1'4, the upper end of which latter is pivotally connected with the pole through the medium of suitable brackets, such as indicated at 18.

fiver the plow standard, a seed can base casting 19 is disposed and supported by links 20, tie latter being pivotally connected at their upper ends with said base casting and at their lower ends to the plow standard. The base casting supports a suit able seed can and also feed mechanism as indicated at 21.

The particular construction of the feed mechanism, whether it be adapted for feed ing corn, cotton seed or other seed, forms no part of my present invention and need not therefore, be specifically described herein. It may be stated however, that the said feed mechanism is actuated by suitable gearing to which motion is imparted by the operation of a transverse driving shaft 22 mounted in suitable hearings on the base casting 19. The shaft 22 projects at both ends beyond its hearings in the base casting 19, and with one projecting end of said shaft, the rear end of a bar '3 is looselv connected,the other end of said bar being mounted on a sleeve 21 mounted loosely upon the horizontal journal member 25 of the arch axle. A uard casing 26 is loosely mounted at its rear end upon the other end of the drive shaft and at its forward end, this casing is loosely mounted upon the horizontal journal member 27 of the arch axle. The bar 23 and guard casing 26 thus constitute connecting means between the two ends of the driving shaft 22 and the arch axle and maintain the former always parallel with the journal members of the latter and always the same distance therefrom. The sleeve 24: is provided with a socket member 28 disposed at right angles thereto for the reception of one arm 2-9 of a rearwardly projecting bail 30,the other arm 31 of said bail being secured in a socketed arm 32 having a sleeve 33 mounted loosely upon the journal member 27 of the arch axle. The-intermediate portion of the bail 80 is pivotally connected with the plow LOO beam 7 by means of bracket arms 3%, so that when said bail is rocked (as hereinafter explained), the plow beam and the various instrumentalities which it carries will be raised or lowered.

An arm projects inwardly from the casting of which the sleeve 2i and socket arm 28 form parts, and to this arm, one end of an adjustable rod 36 is connected,- the other end of this rod being pivotally connected with the upper link 17, at a point between the pivotal connection of said link with the pole l and the connection of said link with the lower link A hand lever 37 is secured to a lug 38 projecting from the sleeve or casting 24:,wvhereby power may be applied for rocking the bail 30 to raise or lower the planting'mechanism, said hand lever being provided with a suitable detent to engage notched segment 39 secured to the arch axle, and the first and second notches l0ll are spaced adistance apart appreciably greater than the distances between the remaining notches for a purpose hereinafter more fully explained. The elongated sleeve or iub portion 42 of a sprocket wheel is loosely mounted upon the journal r ember 527 of the arch axle and this sprocket is connected, by asprocket chain 4% with a sprocket wheel 4-5 on the driving shaft of the seed dropping mechanism,said sprocket wheels and chain being housed within the guard casing 26, and a tightener it? carried by an arm 46 being provided for the sprocket chain.

Mounted slidably upon and rotatably with the extended hub or sleeve 42 of the sprocket wheel L3is a clutch sleeve -I1-7 having clutch teeth l8 at one end to engage teeth $9 on a clutch sleeve 50 also loosely mounted on the axle member 27. The clutch sleeve 50 is connected with the hub of the wheel 3 by means of a suitable number of interlocking collars 51, the collars at respective ends of the series having interlocking relation with the hub of the carrying wheel 3 and the clutch sleeve 50 so that the latter will be continually rotated when the planter is in motion and, when the clutch members are pressed into interlocking engagement by the action of a spring 50 transmit motion through the sprocket gearing above described to the driving shaft of the feeding or dropping mechanism. It will be ob served that the spring 50 is located between the sleeves 4:2 and l7 which rotate together and hence said spring will not be subjected to frictional engagement of a rotating part.

For the purpose of controlling the operation of the dropping mechanism and to cause the source of driving power to be thrown out of action when beam is raised and into action when the beam is lowered, and to effect these results automatically and efliciently, the devices now to be explained are employed. A bracket 52 is secured to an upright member of the'arch axle l and 011 this bracket, a bell-crank-lever 53 is mounted and constitutes the shifting lever forthe clutch. The arm 54: of this bellcrank is bifurcated to embrace the clutch sleeve for sliding the latter out of cooperative relation to the clutchsleeve 50, and the arm 55 of said bell-crank projects freely through a guide loop 56 on the bracket 52, so as to be in position. to be engaged by a cam arm 57 mounted on the arm 31 of the bail 80. The hub portion of the cam arm 57 may, if desired be made integral with the socket member 32 as shown in Fig. 5. The

bracket 52 is provided with an extension 58,

to which the rear end of the'brace 6 is connected,said bracket thus constituting means for connecting said brace 6 with the arch axle. V a

The engaging edge 59 of the cam arm and the distance between the first and second IlOtCl16S lO- l:1 of the segment 39 are so proportioned that when the hand lever 37 is moved forwardly in the act of swinging the bail upwardly to raise the beam'and the detent on said lever moves from the second notch ll to the first notch lO,the said cam arm, cooperating with the arm 55 of the bell-crank, will move the latter a suflicient distance to shiftor slide the'clutch sleeve47 far enough to insure the complete disengagement of its teeth from the teeth of the clutch sleet e 50, and render any accidental reengagement of the clutch members impossible as long as the detent of the hand lever is in the first notch of the segment. On the other hand, the same proportioning of the cam arm and the distance between the first and second notches of the segment will insure full and complete engagement of the ion teeth of the clutch members when the hand lever moves from the first to the second notch of the segment. Such positive and sure engagement of the clutch members will be caused and maintained by the action of the spring when the detent of the hand lever is in the second notch or in any notch in rear of said second notch of the segment, and un der these conditions, the soil engaging devices will be in operative positions and moa tendency to throw the dropping devices out of gear. The reason for the importance for insuring such conditions during the operation of the machine is that when the machine is used for planting corn, the wheels will run on the top of the ground while the soil-engaging member or plow bottom will run from five to seven inches deep, and hence when the lister is working in this position, the raising lever will be thrown to the rear so that the detent will be in the second or third notch from the rear of the segment and when in this position, the engaging edge of the cam arm on the bail will be quite a distance away from the bell-crank on clutch shifter. It will, therefore, be apparent that there will be no possibility of the cam arm throwing the machine out of gear and stopping the seeding or dropping mechanism. When, however, the machine is used for planting cotton, the ground is made up in ridges or beds, and when the wheels of the machine run in the ditches, the hand lever is sometimes used in the second notch from the front of the segment, and with prior constructions considerable annoyance has been occasioned by the slipping of the clutch and sometimes by the shifting of the clutch and the consequent stopping of the dropping or seeding mechanism. My improvements are such that these objectionable operations cannot occur, because it is necessary to move the hand lever from the second to the first notch of the segment in order to operate the clutch devices to throw the mechanism out of action, said clutch devices being, at all other times in positive mesh and the means which controls them being so positioned as not to be capable of accidentally throwing the clutch while the machine is in action.

Slight changes might be made in the details of construction without departing from the spirit of my invention or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. The combination with a frame including an arch axle and carrying wheels, a beam, soil-engaging devices carried by said beam, and seeding mechanism supported by said beam, of a swinging bail loosely connected with the arch axle, a sprocket wheel having a sleeve mounted loosely upon the axle, a clutch sleeve slidably mounted upon and rotatable with the sprocket wheel sleeve, a spring encircling the sprocket wheel sleeve and engaging the clutch sleeve to press it outwardly, a clutch sleeve connected with one of the carrying wheels, means gearing said sprocket wheel with the seeding mechanism, a shifting lever for the clutch, means on the bail for shifting said lever, and means for swinging the bail.

2. The combination with a frame including an arch axle, carrying wheels and a pole, of a beam, and soil-engaging devices carried by the beam, of sleeves mounted upon horizontal portions of the axle and provided with socketed arms disposed at right angles thereto, an arm projecting inwardly from one of said socketed arms, a bail secured to said socketed arms and pivotally connected with the beam, a hand lever secured to one of said sleeves, means for locking said lever, links pivotally connected together and pivotally connected respectively to the pole and beam, and a rod connecting one of said links with the inwardly projecting arm on one of the socketed arms for the bail.

3. The combination with a frame including an arch axle and carrying wheels, a beam, soil-engaging devices carried by the beam, a swinging ball connected with the beam, means for swinging said bail, and seeding mechanism, of a support for the seeding mechanism, a driving shaft for the seeding mechanism mounted on said support, pivoted links connecting said support with the beam, a bar loosely connected with one end of said driving shaft and with the axle, a guard casing loosely connected at one end with the driving shaft and at the other end with the axle, sprocket gearing connecting the driving shaft and axle and inclosed by said guard casing, clutch devices between the sprocket on the axle and one of the carrying wheels, and means for shifting said clutch devices.
